[PATCH RFC] tests/functional: add tests for SCLP event CPI

[Shalini Chellathurai Saroja]

Add tests for SCLP event type Control-Program Identification
(CPI) to s390x CCW virtio tests.

Please note that these tests are skipped as the guest OS does not
trigger the SCLP event type CPI when the command
'echo 1 > /sys/firmware/cpi/set' is executed in the guest. I
believe that the guest OS must to be updated to support the SCLP
event type CPI.
